Hey guys. Have an 03 Yukon Denali shorty with 252k miles. Love this thing! I am having an issue though that I wanted to run by you guys to see if it is common and if there is a fix.
When driving down a road or highway (speed doesn't really matter, but it is a bit worse on the highway) if I hit a bump, like an expansion joint, at the same time with both front wheels the bump is felt and the truck traverses it well. However, if I hit a bump that is not perpendicular to the direction of travel and is say slanted 45* or so to where one of the front wheels hits it first and then the other a split second later the entire body structure feels like a wet noodle and there is visible and alarming cowl shake.
Can this be attributed to worn body mount bushings? Or is it just a problem with this chassis and the age? Any frame sitffeners out there?
For mods, I have had three different suspensions on it and I have felt this issue with all of the suspensions. Currently I have it lowered 2" on beltech lowering spindles and springs with Beltech shocks.
